I been clamping for about 3 months atleast 3-4 days a week and had no gains. Even struggled to get an erection at times. I used to do horse440s with my hands and even though I didnt get much gains from them they did keep my EQ high. So I tried them in the clamp for about 12 mins. Squeeze the head forcing blood into the shaft for 1 min and edging for 1 min. Tonight I got a hard on like I normally used to get before regular clamping. Is this a sign to stick with this exercise? I also did 5-20 sec intense stretches before the clamped horses.
